OK, I'm getting there, it works...  But I have a problem with
control()'s interface: it is declared as variable arguments in vf.h,
and it looks like it is supposed to call the fallback vf_next_control.
But of course this is not really possible with variable arguments...
I think I am missing part of the picture.
